Started looking at setting up my channel configuration on the weekend and it made me wonder about how data is sent through the 1.31 network. With my controller (Pixlite 16) I have the ability to start an output at a particular channel in a universe but can this cause data transfer inefficiencies. I understand it is good in terms of utilising all channels and minimising the number of universes required. However, at this stage I don't have that many pixels (1138 to be exact). Is it more efficient for the computer to send data so that each output starts at a new universe. This would prevent the need for say the first 100 channels of universe 2 being sent to output 1 and then the subsequent 410 channels being sent to output 2. Is there any benefits/risks associated with setting up universes for outputs. I understand this has the potential to waste many channels in a universe. Do all channels in a universe get sent in a "packet" regardless of if they are used. You will notice from the rambling unorganised way this question is written I have no real understanding of how data is formed/grouped/sent/received but I just thought I should try and get into good set up habits now before (hopefully) things start to get bigger over the years.
